ISO 19650 BIM Execution Plan (BEP) & CDE Governance: Standards, Scope & Fees

Multi-million-dollar developments fail digitally when ten consultants model with incompatible origins, rogue family parameters, and chaotic file names. SerMimar acts as your ISO 19650 Information Manager—authoring enforceable EIRs, BEPs, and automated Solibri/Revit validation rules.

Engineered to ISO 19650 EIR / BEP precision across a reference benchmark of 10,000 – 250,000+ m² under BS EN ISO 19650-1/2/3/5 · UK BIM Framework · COBie, this canonical specification unifies spatial design, multidisciplinary clash resolution, and 5D cost certainty prior to site mobilization.

Structural Grid & Modular Alignment: Master Project Base Point, Survey Point, True North rotation, and multi-building zone/volume breakdown strategy.

Primary column grids, facade mullion subdivisions, and subterranean parking geometry are locked onto a unified datum—eliminating non-standard off-cuts and costly site framing adjustments.

Spatial Program & Net-to-Gross Efficiency: Level of Information Need (LOIN) matrices defining exact geometric and alphanumeric parameters required at each project stage.

Live parametric Revit area schedules track net usable/leasable floor area against vertical cores, MEP plantrooms, and envelope wall thickness at every design iteration.

Vertical Cores, Logistics & Life-Safety Egress: Uniclass 2015 / OmniClass spatial and room numbering schemas mapped seamlessly to facility management CAFM systems.

Travel distances, pressurized stair cores, ADA/accessible routing, and heavy service/loading dock swept-path geometry are validated against NFPA, EN, and local building regulations.

Subsurface Utilities, Drainage & Wet Shafts: Standardized system classification codes across civil utilities, drainage networks, and district energy corridors.

Gravity stormwater and foul drainage stacks are modeled with true 1.5%–2.0% invert slopes, locking structural beam web penetrations and acoustic riser sleeves before rebar detailing.

Domestic Plumbing, NFPA/EN Sprinkler & Hydronics: Golden Thread fire-safety asset tagging (fire doors, dampers, suppression valves) per ISO 19650-5 & UK Building Safety Act.

Wet/dry sprinkler grids, fire hose cabinets, booster pump skids, and hydronic manifolds are spatially coordinated above ceiling plenums without compromising architectural clear heights.

HVAC Routing, Acoustics & Zero-Clash Verification: Automated model-health & clash gate checklists enforced before any consultant container transitions from WIP to Shared.

Automated Navisworks and Solibri rule-sets enforce ±3 mm hard-clash tolerances and 25–50 mm insulation/maintenance clearance zones, closing 100% of BCF issues prior to tender issue.

Structural Framing & Seismic Engineering: Material grade, carbon-factor (embodied carbon kgCO2e), and structural load-bearing IFC property set mapping.

Inter-story seismic drift ratios, ductile steel moment/braced connections, foundation punching shear, and secondary facade subframes are signed off by our senior structural engineering partners.

Building Envelope & Hygrothermal Physics: Thermal transmittance, acoustic rating, solar heat gain (g-value), and warranty metadata embedded into curtain-wall families.

2D/3D thermal-bridge condensation risk is audited per EN ISO 6946, pairing Class A1 mineral-wool insulation, vapor-permeable membranes, and slotted seismic facade brackets at 1:5 shop detail scale.

Georeferenced Masterplan & ISO 19650 CDE: Turnkey configuration of Autodesk Construction Cloud (ACC), Trimble Connect, or Dalux permissions, naming syntax, and status suitability codes (S0–S4, A1–An).

All discipline models share true survey coordinates (UTM / National Grid) and progress through ISO 19650 WIP → Shared → Published gates inside the Common Data Environment.

Native BIM & Construction Documentation Package: OIR/AIR/EIR documents, Pre & Post-Appointment BEP, Responsibility Matrix, MIDP/TIDP trackers, Revit template (.RTE), and Shared Parameter file.

Clients receive unlocked native EIR · Pre/Post-Contract BEP · MIDP/TIDP · CDE Templates source files, plotted PDF/DWG construction sets, and signed zero-clash audit certificates.

5D Quantity Take-Off (BoQ) & Indicative Studio Fee: The indicative engineering & BIM fee band for this reference scope is $6,500 – $18,500 (Governance & Setup Package) (with indicative construction CAPEX benchmark at Multi-Building / Institutional Portfolio Governance). Prevents costly mid-project remodeling and guarantees tender bidders price identical, auditable 5D data structures.

DfMA Prefabrication & Export Execution Pathways: Embeds fabrication work-package IDs, container batch codes, and erection sequence parameters into the master BIM schema.

Clients may tender the open BIM package to any local contractor or leverage our integrated group factories (SerBuild steel structures, SerMimar İskele EN 12810 scaffolding, SerMimar Şömine hearths, and SerSourcing 40HC consolidation).

International Codes, Sustainability & Compliance: 100% aligned with BS EN ISO 19650 Parts 1, 2, 3 & 5, UK BIM Framework, and public-sector digital procurement mandates.

Structured directly for LEED / BREEAM / RE2020 energy modeling, UK Building Safety Act Golden Thread compliance, Eurocode National Annexes, and institutional lender due diligence.
